WEATH ER-STRIP.

SPECIFICATION forming part of Letters Patent No. 435,841, datedSeptember 2, 1890.

Application filed November 1, 1889. Serial No. 328,903- (No model.)

To all whom it may concern.-

Be it known that 1, JOHN E. JONES, of New York, in the county and Stateof New York, have invented a new and Improved VVeather- Strip, of whichthe following is a full, clear, and exact description.

My invention relates to a weather-strip designed more particularly forwindows; and the invention consists, principally, of a strip of springmetal bent longitudinally to be U- shaped in cross-section, applied tothe edge of the sash, so that the outer part of the strip will pressconstantly against the window-frame.

The invention also consists of similar strips at the top and bottom ofthe sash and at the meeting-rails, all as hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a broken front elevation of a window-frame and sash havingInyinvention applied thereto. Fig. 2 is a sectional elevation of thesame on line 00 x of Fig.1. Fig. 3 is a sectional plan view on line 3 yof Fig. 1. Fig. 4 is a detailed section on line .2 z of Fig. 1, and Fig.5 is a detailed perspective view of one corner of the sash andweather-strip removed from the frame.

Along each side of the sash A is attached a weather-strip B, of sheetmetal, preferably spring-brass, bent longitudinally to be substantiallyU-shaped in cross-section. The preferred form is shown clearly in Fig.5, the plate being bent to form the member I), the outer member Z), andthe curve b The member Z) is pressed into a slot 0, formed in one of theouter surfaces of the sash parallel with and a short distance from thevertical edge of the sash. This slot forms a bridge a, which re-enforcesthe spring and preventsinjurious crushing or buckling of the spring atany part. This bridge acts as a cleat to retain the strip in place, andthe strip fits over it, so that the upperpart of the bridge reaches upto the fold in the strip, and it at all times keeps the fold from beingcrushed by any side pressure that may happen to come upon the sash.

In a recess c, formed in the front edge of the meeting-rail O, is fittedthe strip D, of spring metal. This is substantially U -shaped incross-section, with a flange (1 to fit in aslot in the sash, as shown inFig. 2. The outer member d by its spring action presses against the railE, and forms a tight point when the sashes are closed.

At the top of the windowin aslot dis fitted the metal spring plate orstrip E, formed with a groove e, which deflects the outer edge of theplate downward to form a close contact with the upper edge of the sash,and at the window-sill is fitted in aslotf asimilar strip F, which isslightly grooved at f to normally elevate the outer edge of the strip,so it will have a sufficient spring-pressure against the bottom of thesash when closed to exclude air, dust, snow, rain, &c.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is

1. A sash formed with a slot in one of its outer surfaces, forming abridge at the corner of the sash combined with a metallic strip U shapedin cross-section, one of the members of the strip being inserted in thesaid slot, substantially as described.

2. A weather-strip composed of a ribbon of sheet metalbentlongitudinally into U shape, in combination with a sash formed witha slot in its outer surface near to and parallel with the edge of thesash, one member of the strip being inserted in the slot, the otherbeing held by spring-pressure against the windowframe, and the curve I)acting as a frictionsurface against the window-cleat, substantially asdescribed.
